This paper investigates the use of Ethernet/IP communications protocol for data acquisition and control of electrical networks in an industrial environment. A high-speed communication connection among all the devices operating in a distribution network using breakers, contactors, relays, power meters and other devices may allow a large amount of data to be exchanged to and from an industrial/utilities...
This paper presents a LabVIEW-aided PID designed controller to monitor DC motor speed and uses the software simulation of VisSim to analysis its response. First, design the drive circuit of DC motor and as the feedback signal through the photo sensor and 8051 chip modules to produce rotational speed signal, and show from SEG7 displays. To take out the analog signal through D/A converter at the same...
The paper illustrates the electrical stations of medium voltage in which there is going to be implemented an automated multivariable system, based of software packages for data acquisition, storing, data transmission, processing, monitoring, analysis and which to allow the monitoring of a large number of parameters. The purpose of the local data acquisition, protection and control equipment and of...
